The CVEN speakers were designed by the Vibe Research and Development team of UK and European engineers headed by company founder Carl Venables.

The design brief was to create both a two way and a three way component speaker that delivers a realistic reproduction of recorded sound.

Each component of the system is matched and balanced to produce a linear frequency response which enables the listener to appreciate music as the artist originally intended.

CVEN62C-V4 CVEN63C-V4

THE RANGE

The CVEN 6 has a wide and flat frequency response, enabling it to be common to both a two way and three way component kit.

The midwoofer is designed to overcome the inherent problems of every loudspeaker design: distortion, power handling, dynamic response and efficiency.

VIBE understand that the key to high quality audio reproduction is matching and balancing the magnet, basket, voice coil, spider, cone and surround.

With twenty two years of design experience we believe we have created our best sounding loudspeaker to date.

CVEN 6 MIDWOOFER

• Aluminium field-stabilizing ring inside magnet assembly for reduced high-level distortion

• Vented voice coil former for reduced distortion and compression

• New vented chassis for lower air flow speed reducing audible distortion

• Heavy-duty black fibreglass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level details

The CVEN 1 features a 22 mm voice coil and wide surround which delivers an extended bandwidth that would usually require multiple drivers to achieve.

Featured with a rear chamber these compact tweeters offer very low resonance frequency which further increases the tweeters ability to produce frequencies thought impossible by a driver of this size.

In order to keep distortion and resonance frequency low the CVEN 1 Tweeter is designed around an external neodymium ring magnet in order to allows for a larger internal volume than that of traditional neodymium tweeters providing improved frequency response .

CVEN 1 TWEETER

• 22 mm design for optimal compromise between on- and off-axis frequency response, resonance frequency, and power handling

• Rear chamber for low resonance frequency and reduced distortion

• Outside ring neodymium magnet for lower resonance frequency and distortion

• Precision-coated textile diaphragm for improved consistency and high-frequency extension

• Optimized dome shape for ultra high frequency cutoff


• Copper-clad aluminium voice coil wire offering lower moving mass for improved efficiency and transient response

• Build-in cavities under dome/edge to equalize pressure for lower distortion and lower resonance frequency

• Flexible lead wires for higher power handling and larger excursion

• Large hexagon mesh grille secured by the magnetic force of the motor allows easy removal for ultimate purity of sound

• Gold plated terminals to prevent oxidation and ensure long-term reliable connection

Many speaker designs hide behind a veil of crossover components which can add colour and reduce efficiency in even the best engineered product.

The CVEN two way system is different. An exquisitely designed and tuned tweeter purposefully matches the roll off frequency of the CVEN midwoofer.

In doing so it produces an almost linear frequency response without the need for a crossover.

PASSIVE CROSSOVER

Protection is the only requirement, therefore, a Mundorf reference capacitor is included in each kit.

A three way system requires much more filtering, however, our philosophy is to use only a single Mundorf reference capacitor to provide protection for the tweeter with a polyswitch added as an additional safeguard.

There is an optional 90Hz high pass filter selectable via high current gold plated jumpers adding further functionality.

• Single Mundorf reference capacitor for tweeter high pass filter

• High current gold plated Jumpers

• Selectable 90Hz 6dB high pass filter for the low frequency channel

• Inductor coils specifically orientated to provide minimal crosstalk and improved sound quality.

• High grade plexiglass top cover

• Gold plated screw down speaker connectors prevent oxidation and ensure long-term reliable connection

NOTE :

In most situations the tweeterwired out of phase with the midwoofer will produce the most natural sounding vocal performance.

It is recommended that experimentation of both in phase and out of phase configurations in the vehicle is required in order to achieve the best results.
